How many feet do you need opposite 68 feet to make one-half acre?

Answer 1

I assume you want a rectange of dimensions 68 times (unknown). Here is how you solve it.

1) Look up the definition of "acre"; specifically, how many square feet does an acre have (unless you have already memorized it, of course).

2) Convert the half-acre to square feet.

3) Divide the number of square feet by 68 feet to get the unknown other length.
